DPT 2 - Priority Switch
DPT 2 has three outputs in Value Inputs and four inputs in Value Outputs. To set a value on a Value Output, you can either send one integer on IN (recommended), or two booleans to SWITCH and PRIORITY (in this case, additionally using the TRIGGER input is recommended).

DPT 3 - Dimming
DPT 3 has three outputs in Value Inputs and four inputs in Value Outputs.
-
Direction as boolean. True for upwards and false for downwards.
-
Step width as Integer. For the sending, the exact values for the step width are expected.
-
Possible values: 1

-
32
-
64
-
-
Stop as boolean. A true is sent / received for stop. For the start, a false is also issued.
DPT 10 - time
DPT 10 has four outputs in Value Inputs but six input values in Value Outputs. For the conversion into a KNX telegram, the transfer of a timestamp is possible.
|

No / Yes |
Timestamp - the timestamp is used in order to send the timestamp in compressed form in one go. The timestamp can be taken from the Clock, for example. This is a so-called UNIX timestamp which corresponds to the seconds since 01.01.1970. |
|
DOW |
Yes / Yes |
Day of week. 1 for Monday to 7 for Sunday |
|
HOUR |
Yes / Yes |
Hour 0 - 23 |

MINUTE |
Yes / Yes |
Minute 0 - 60 |
|
SECOND |
Yes / Yes |
Second 0 - 60 |
DPT 11 - date
DPT 11 has three outputs in Value Inputs but five input values in Value Outputs. For the conversion into a KNX telegram, the transfer of a timestamp is possible.

|
YEAR |
Yes / Yes |
The period between 1990 and 2089 can be processed via KNX |
|
MONTH |
Yes / Yes |
Month of the year 1 for January until 12 for December |
|
DAY |

DPT 18.001 - scene control
DPT 18.001 has two outputs in Value Inputs but three input values in Value Outputs.
|
Name |
Output / Input |
Description |
|---|---|---|
|
TRIGGER |
No / Yes |
See Value in-/output |
|
SAVE |
Yes / Yes |
Indicated whether this is an Activate or Save command as boolean (false: activate, true: save) |
|
SCENE |
Yes / Yes |
The number of the scene. Note: in accordance with the recommendation from the KNX specifications, LOGIKEDITOR uses the 1..64 range, while supporting 0..63 on the KNX side. Thus, if you send or receive value 1, the actual telegram will contain value 0. |
To send a scene control command, the use of the TRIGGER input is recommended. Otherwise a telegram is issued with every incoming value, which can lead to the activation or saving of the wrong scene number.
DPT 232 and DPT 12.600 - Colour
Three and four byte colour.
The 12.600 type is not part of the KNX specification. It is required for the DUODMX GATEWAY in order to be able to control the corresponding RGBW light there.
